In other words, if someone dropped an object in midair and it didn't fall to the ground would scientific theories like the theory of gravity need to be re-examined (obviously not rejecting the observed effects and behaviors we are already accustomed to witnessing, but to expand our understanding of how gravity works and eliminating the notion that an object of any mass must ALWAYS fall to the ground when dropped). Or would we just categorize it as "supernatural" and unrelated to existing scientific understanding and current models?

I just recently went to 7th grade (I can't believe they're making us work after 3 days of school :S I thought they needed to know one another? How cruel.) and I'm now studying the universe, which freaks me out cruely. I hate mysterious things. I read an article that I had to read for school, what happened before, but there was also articles about the future that I didn't have to read. It loooked interesting, so I read it. Apparently, Galaxies collide to one another, they seperate from one another, the "Stellar Era" ends, the "Degenerate Era" will happen along with the "Black Hole Era" (Oh boy :S I hate black holes) and the Universe dies after that (The "Dark Era")

I'm just wondering, the article is really confusing :S (You know, when you read something and its so complicated and intended for smart people) so if im missing any other "-- Era" please tell me and a brief article about it? Also, can you tell me more about the Eras I stated above? Thanks :D

You are driving into St. Louis, Missouri, and in the distance you see the famous Gateway-to-the-West arch. This monument rises to a height of 192 m. You estimate your line of sight with the top of the arch to be 3.1° above the horizontal. Approximately how far (in kilometers) are you from the base of the arch?

It is dark green in the centre and the outside is light green, and it is completly transparent. I found it on a beach at lake huron. It was out pretty far were it was wavy and there were no other rocks (the other rocks probably got eroided), so I'm guessing it's pretty hard (an 8 - 9 on the mohs hardness scale). It's approximatly 30 carats. Could it be an emerald?
